Add emoji like event handling to core and onebot

Introduces a typed event emitter for app events in napcat-core, specifically for emoji like events in groups. OlPushService now emits 'event:emoji_like' when a group reaction is detected. napcat-onebot listens for this event and emits corresponding OneBot events. Refactors and adds missing type definitions and improves method formatting for consistency.
